Calculate
You press this button when you have finished the data entry.
Using the data entered in the "New" topic. After we click the Calculate button we get the following:
You will see the misclose distance is 44.127 which is obviously incorrect. For this data we have entered the data in clock-wise order. You can see that line 3 is out by 180 degrees. To fix we need a value of 189~ etc. The app has a shortcut key. Left click into the cell on line 3 under bearing. Now press the "r" key. This is short for reverse and reverses the bearing. If you now recalculate you will see that we now have a misclose of 0.003 meters, which is within our tolerance.
